UHPLC Column Protection Extended to Widepore Columns
29 Mar 2012

Phenomenex Inc. has introduced the new SecurityGuard™ ULTRA to protect widepore (≥200 Å) UHPLC columns typically used in the analysis of biomolecules. The SecurityGuard ULTRA system extends the lifetime of columns packed with sub-2 micron fully porous or core-shell particles by protecting against the damaging effects of chemical contaminants and microparticulates introduced by the sample, mobile phase or system. These contaminants can also affect method sensitivity, quantitation and peak identification.

The new SecurityGuard ULTRA product is ideal for virtually any manufacturer’s UHPLC, sub-2 micron or core-shell widepore columns including the Phenomenex Aeris™ widepore XB-C18, XB-C8 and C4 products. By reducing the frequency of column replacements, as well as the need for troubleshooting and system down time, SecurityGuard ULTRA saves chromatographers time and money. Pressure-rated up to 20,000 psi (1,378 bar), these widepore guard cartridges have no significant impact on chromatography, backpressure or dead volume.

“The easy-to-use SecurityGuard ULTRA protects columns without affecting the performance advantages of UHPLC, sub-2 micron and core-shell widepore particle technologies,” explains J.T. Presley, product brand manager for Phenomenex.

Phenomenex offers an interactive web application through which users can enter their UHPLC, sub-2 micron or core-shell column information to find the right SecurityGuard ULTRA column protection system. Helpful videos are also available providing instructions on how to properly install and use the SecurityGuard ULTRA column protection system.
